Improvement in millstone exhausts

lNlPllQllEllvlEhlTl IN MILLSTNE EXHAUSTS.

The Schedule referred to in these Letters Patent and making part of thelame.

To all 'whom-it may concer-n: l

Be it known that I, JACOB LINGENFELTER, ef Bloody Run, in the county ofBedford and State of Pennsylvania, have invented a new and valuableImprovement in Millstone Exhaust; and I do` hereby declare that thefollowing is a full, clear, and exact description'of the coi'istructionand operation of thev same, reference being had to the annexed drawingmaking a part of this specification and tothe letters and figures efreference marked thereon.

Figure 1 of the drawing is a side view of my improved exhaust-pipe.

Figure 2 is a front View of the same.

My invention is an improvement upon the apparatus for which Letters-Patent of the United States Wee granted to David Baird, December, 1867;an

It consists in the means provided for saving any dust or fine lour whichmay be drawn up by the eX- hanet, and for carrying oli` the condensedsteam and moisture. l

The letter A of the drawing represents the runner.

' C, the exhaust-pipe, provided with the expanded chamber D at its lowerend.

E designates the upper expansion leading to the fan; and

F the waste-pipe or conduit which conveys away the condensed steam andmoisture.

G represents an elbow or inclined section of the exhaust-pipe, designedto cause the water of condensation to flow back into the funnel a of thewastepipe F.

The object of `expanding the lower end of the exhanstfpipe is to effecta slow draught in this portion,-

thereby giving the line particles of floundust which are drawn upwardwith the steam sniicient time to enable them to become dampened byitscondensation, thus acquiring snicient weight to cause them to fall.

Thus a great saving is accomplished, and this expansin or chamber D isso well adapted to the object in view that flour-dust is never carriedbeyond the rst bend in the pipe, andv therefore both the elbow Gr andthe pipes and chambers above it are never coated, but always bright andclean. l

rlhe chambers andpipe abovethe elbow G being suitably arranged, all thewater of condensation is conveyed back into this portion of theV pipeand runs alen g its inclined bottom into the funnehshaped mouth of theconduit F, whereby it is carried wherever it may be desired. v

By these simple devices the millst-one exhaust is rendered efficient and`economical. Time and labor are saved, as well,` as a great quantity ofthe finest quality of flour.

What I claim as my iuvention,.and desire to secure by Letters Patent,is-

' l. At the lowei' end of a'umillstone exhaust-pipe,4

the enlarged chamber D, when constructed and arranged to operate in themanner and for the purpose shown and described.

2. In combination with the expanded chamber D, at the lower end of amillstone exhaust-pipe, the inclined elbow G and waste-pipe F, asspecified.

In testimony' that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
